MMM Temp without Fan? - RC-Monster Forums

BrianG, I really don't understand your hatred (and it is a hatred!!) of fans. Placing a fan on a heatsink drops temps by 20-30F. Cooler is more efficient, correct? Why is this bad?

Pics of Novak fan installed. I'm not going to bother trying it out unless my Castle fan fails.

I don't hate fans....unless they are used where they don't belong. I use fans in my PC (although I'd like to get rid of these). I use fans to keep me cool. If the fans fail in either of these, I can easily tell right away. But neither of these are subjected to the very harsh conditions (vibration, impacts, debris) these vehicles are subjected to.

I have always been of the opinion that a properly selected and geared system should never see high temps. None of my setups use fans (even my two Quarks) and I haven't seen temps over 130*F. The only exception is my CRT.5 but that's because the 4600 motor is simply too small for the truck (I get temps around 150*F, but that's too high).

Also, if you are relying on a fan to keep your system operational, then that is just a recipe for disaster considering that it is sometimes difficult to know when a fan fails until it is too late.

Usually, mechanical components break first, and fans are no exception.

Besides, you already have a source of flowing air because the vehicle is MOVING (usually at a decent speed). A little ESC mounting fore-thought and maybe a little extra heatsinking is just as good as a fan without the hassle and risk.

yeah you sure should not 'depend' on the fan. however, everthing else equal an additional fan will help to keep the components even cooler. if the fans are correctly mounted they won't fail easily. those little fences that are available help a lot for the long living of those little fans.
